#- 3.45 - 2.3 (8.6) div 0.5#
Rearrange!
#-3.45/100 - 2.3/10 (8.6/10) div 0.5/10#
#- 345/100 - 23/10 (86/10) div 5/10#
Using the rule of BODMAS..
Therefore we'll solve the Bracket and Division First!
Bracket!
#- 345/100 - (23 xx 86)/(10 xx 10) div 5/10#
#- 345/100 - 1978/100 div 5/10#
Division!
#- 345/100 - 1978/100 div 5/10#
#- 345/100 - 1978/100 xx 10/5#
#- 345/100 - 1978/cancel100_10 xx cancel10^1/5#
#- 345/100 - 1978/10 xx 1/5#
Multiplication!
#- 345/100 - 1978/10 xx 1/5#
#- 345/100 - (1978 xx 1)/(10 xx 5)#
#- 345/100 - 1978/50#
Subtraction!
#- 345/100 - 1978/50#
Taking LCM..
#(- 345 - (2 xx 1978))/100#
#(-345 - 3956)/100#
# - 4301/100#
